New Paper “Problem Specific Classical Optimization of Hamiltonian Simulation” published in Physical Review Research
We are glad to announce that our paper on “Problem Specific Classical Optimization of Hamiltonian Simulation” has been published in Physical Review Research. In our paper, we introduce a variational algorithm for Hamiltonian simulation. As quantum optimization faces fundamental problem when performed on a quantum machine, we studied optimization on a classical computer. As opposed […]

Quantum Computing on Current Hardware – Prof. Michael J. Hartmann’s inaugural lecture
How can we compute or simulate the time evolution of quantum many-body systems on near-term quantum computers? This is currently one of the most pressing questions in the field. Prof. Michael J. Hartmann gave his inaugural talk on “Quantum Computing on Current Quantum Hardware” on the 5th of July discussing quantum simulation as a candidate […]

Tunable coupler to fully decouple superconducting qubits
A major bottleneck of current NISQ hardware is low fidelity of 2 qubit gates. A component to improve this is the possibility to completely switch off interactions between qubits. In our pre-print we derive conditions for the coupler to suppress all parasitic interactions, i.e. state delocalization and ZZ-crosstalk. We then develop a coupler model for […]

Problem Specific Classical Optimization of Hamiltonian Simulation
In our latest pre-print, we introduce a variational algorithm for Hamiltonian simulation. As quantum optimization faces fundamental problem when performed on a quantum machine, we studied optimization on a classical computer. As opposed to prior work, the presented algorithm is applicable to any local Hamiltonian and does not require symmetry constraints. The authors show that […]

Large-scale simulations of Floquet physics on near-term quantum computers
Timo Eckstein, Refik Mansuroglu, Piotr Czarnik, Jian-Xin Zhu, Michael J. Hartmann, Lukasz Cincio, Andrew T. Sornborger, Zoë Holmes Quantum systems subject to periodic driving exhibit a diverse set of phenomena both of fundamental and technological interest. However, such dynamical systems are more challenging to simulate classically than their equilibrium counterparts.
